[BUG] wifi_channel_sensor provides decimals on whole number

[HACS-bank]

Before you start

• I searched existing issues for similar reports.
• I tested against the current website or a recent release or development build. If I could not, I explained why below.

Area affected

Home Assistant or controller integration

Firmware

ESPHome

Installation or connection

ESPHome local build

ESPectre version or commit

3.0.0 rc2

Board and chip

NSpanel

Controller or integration

Home assistant 2026.9.xx

What happened?

The WiFi channel (which is an integer e.g 4) is reported to HA as floating point (e.g 4.0)

What did you expect to happen?

Channels are not scalar, should possibly be a string "4"

Steps to reproduce

Check ESPhome device in HA Devices
Press refresh diagnostics

Hi @HACS-bank . Fixed in 11de0b0, included in 3.0.0-rc3.

The Wi-Fi channel remains a numeric sensor, but Home Assistant should now display it without decimal places, for example 4 instead of 4.0.

Could you update to rc3 and confirm that it displays correctly after refreshing diagnostics?
